LOUIS E. NELSON, OF OABERY, ILLINOIS.

WINDMILL-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 437,712, dated October '7, 1890.

Application filed May 29, 1890. Serial No. 353,645. (No model.)

To all whom it may concern-.-

Be it known that I, LOUIS E. NELSON, a citizen of Norway, residing at (Jabery, in the county of Ford and State of Illinois, have invented a new and useful IVindmill-Regulator, of which the following is a specification.

This invention relates to windmills, and more particularly to the regulators thereof, and the object of the invention is to improve the construction of devices of a similar general character heretofore existing.

To this end the invention consists of the specific and detail construction and arrangement of parts hereinafter morefully described, and illustrated in the drawings, in which- Figure 1 is aperspective view of a windmilltower with my improved regulator in position therein, showing the relative'location of parts. Fig. 2 is an enlarged side elevation of the regulating device proper, showing the pawls as in engagement with the teeth of the regulator-bar. Fig. 3 is a similar view showing the regulator-bar as down, in which position of parts it will be understood the wheelis out of the wind. Fig. 4 is a cross-section above the spring which throws the pawls into engagement with the regulator-bar.

Referring to the said drawings, the letter IV designates the windmill-tower, which may be of any preferred construction, and P is the pump-rod, which is reciprocated vertically by the rotation of the wind-wheel.

R is the regulator-rod, by means of which the wheel is thrown out of the wind, as is common in devices of this character. To the lower end of this rod is secured aplate N, having notches in its opposite edges, and having a ring a in its lower end, by means of which it may be drawn upon by hand to throw the wheel out of the Wind.

E is the baseplate, secured to a cross-bar of the windmill-tower in any preferred manner, and L is a lever, pivoted at Z, near the lower end of this plate, and its outer end engaging aloop Z on the pump-rod.

p are pawls, pivoted to the lever L at each side of its pivot Z, their lower ends engaging the notches in the opposite edges of the bar N and their upper ends being connected by links K to an operating-lever O, which is pivoted, as at 0, midway between its connections with the links to the base B.

The upper end of the operating-lever O is connected by a rod 15 with a bell-crank lever A, which is pivoted at its angle upon the edge of the tank T, the other arm of the said lever being also connected by a rod 25 with a float F within the tank. The lower ends of the pawls p are pressed normally inward and into the notches by a spring S of about the construction shown in Fig. 4. Such pressure tends to separate their upper ends, thereby moving the operating-lever O and drawing upon the rod t to partially lift the float F. The weight of the latter, however, is sufiicient to overcome the force of the spring S when the water in the tank falls.

The operation of this device is thought to be obvious. As the pump-rod P reciprocates, the tank is filled, and when the float is raised to the limit it is desired the water shall reach the operating-lever 0 will be permitted to turn so far by the force of the spring S that the pawls 19 will engage the notches in the bar N. As the pump-rod P continues its reciprocation, these pawls, then alternately engage and disengage the bar N and draw the same downward, thereby pulling upon the regulating-rod R and gradually turning the wheel more and more out of the wind until it ceases to revolve. The water having fallen in the tank, the float draws on the operating-lever O, and the links K draw the upper ends of the pawls p inwardly and throw their tips out of the notches, and the spring R then raises the regulator-rod, which is released from the regulating device. one that the wind-wheel can be turned out of the wind at any time by drawing downwardly on the ring a, and if it be desired to stop the wheel for any length of time this ring can be hooked around some device which will hold the bar N in this position. It will also be obvious that the vertical reciprocation of the pump-rod works the lever L at all times around its pivot Z, and also raises and lowers the pawls p; but when such pawls are drawn inwardly by the operating-lever, as shown in Fig. 1, their tips are out of engagement with the teeth and therefore the movements of the le ver L are not communicated to the bar N.

What I claim is- 1. The herein-described windmill-regulator, the same comprising a base, a notched bar It will be obviconnected to the regulator-bar and sliding against the base, a lever pivoted to said base and its outer end connected to the pump-rod, pawls pivoted between their ends to said lever at each side of the base, an operating-lever pivoted to the base, links connecting the upper ends of said pawls with the operatinglever on opposite sides of its pivot, and a rod connecting the upper extremity of the said 0perating-lever with a float in the tank, all operating substantially as set forth.

2. The herein-described Windmill-regulator, the same comprising a base, a notched bar connected to the regulator-bar and sliding against the base, a spring for raising said 7 regulator-bar and a ring at the lower end of the latter, alever pivoted to the base and its outer end connected to the pump-rod,pawl s and a rod connecting the upper extremity of said operating-lever with a float in the tank, all operating substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

LOUIS E. NELSON.
